Dong Jinlu synthesized a kind of water suitable foams of polyether polyols using four bromine alcohol as flame retardants, and got flame retardant PUF with the solid-liquid fuel agents in a complex system.
And then they put in the inorganic flame retardants, water-soluble adhesives, inorganic dispersants, intensity strengthening agent, water and foaming agent.

Thus, humanity is at risk especially as current studies reveal that the entombment of plastic waste engenders water, soil, and air pollution, as microplastics and nano-plastics manifest the propensity to disperse in the atmosphere [22].
In the dissolution stage, alkaline activators (M+(aq) + OH-(aq), where M = Na or K) dissolve the solid alumino-silicate material in the presence of water to form silicate and aluminate ions under a controlled pH.
The ion species then migrate to an equilibrium position with the elimination of a small amount of water and they interact by undergoing gelation/coagulation to form an aluminosilicate gel (Gel 1).
In summary, an optimal mixture was identified with a 6 % alkali dosage, a silicate modulus of 1.6, and a water-to-binder (W/B) ratio of 0.3, taking into account both mechanical properties and environmental considerations [37].
Educating and training construction professionals is essential to foster understanding and confidence in the use of geopolymer concrete.

Scarcity of talents in enterprise information, while in the process of enterprises normalization in the future, including in electronic commerce, whether the enterprises building their own or outsourcing, you need to understand what normalization as well as familiar with business professionals[2].
The order determined by the e-commerce into the plan, released to the last operation, through exclusive back pull the water line on-time production, system forming operations of logistics and information flow of the central nervous system, total quality control guarantee the quality of products.

Tammy (2009) points out that wellness strategies are emphasized for promoting the connection between personal or professional health and well-being through collaborative programs and initiatives within organization.
As for working environment, most faculty members are satisfied with natural environment of workplace but feel worried about air noise and water pollution from gabage plant though much more improved since the treatment work has been done.

Temperature at the far end of the steel sheet and the water temperature inside the copper-chromium-zirconium electrodes were both assumed to be 20°C.

Previous management of disaster prevention and relief mainly belonged to the administrative mechanism from up down that relied on operations of professionals, therefore, blinds spots for community prevention were easily generated, to carry out disaster prevention education of community disaster prevention planning through participation of the public, i.e., to promote the public to participate in the drafting of Community Based Hazard Mitigation, communities will be safer; and upon major disasters, shown administrative measures fail to be taken in time, the victims in disasters can also be effectively relieved.

They value blood relationship, such as the concept of "blood is thicker than water", emphasize the security and warmth of the family, such as the concept of "east or west, home is best,” “falling leaves settle on roots.”
In addition, it is necessary to develop free pre-school education, vocational and technical education and widely develop cultural and professional training for the aged people to eliminate adult illiteracy and improve their quality and ability in the modern professional and in the old-age care. 5.

Although meeting the regulations of the time, early buildings are prone to fire hazards, such as damages to the fire zones, changes of floor entrances and exits, locked emergency exit doors, blocking of entrances and exits by vehicles, increased fire sources, dense population in the buildings, due to insufficient professional knowledge and technology in fire prevention.
(4) Proximal water source of the building has inadequate supply capabilities

AMD can severely contaminate groundwater and surface water ecosystems [13, 11].
By compressing waste into dry stacks instead of using water-based storage, this approach minimizes the risk of tailings dam failures and reduces water pollution.
These pollutants significantly impact soil, air, and water quality.
Mining operations also face the challenge of high energy and water consumption, particularly in arid regions where water scarcity exacerbates sustainability concerns. [9] emphasize that mining activities require substantial water and energy inputs, leading to long-term environmental degradation.
The survey was administered to a purposive sample of 60 professionals across various stakeholder groups in the mining sector, including engineers, environmental scientists, sustainability officers, and policymakers.
